Dial Test Indicator

A dial test indicator, also known as a lever arm test indicator or finger indicator, changes the linear displacement of spindle into the angular displacement of indicator with the help of gear rack and gear drive. It’s mainly used to measure the geometric tolerance and dimensions of workpiece, or used as a part of some measuring devices. A dial test indicator has a smaller measuring range than a standard dial indicator and therefore has the ability to measure in smaller increments. A test indicator measures the deflection of the arm, the probe does not retract but swings in an arc around its hinge point. The lever may be interchanged for length or ball diameter, and permits measurements to be taken in narrow grooves and small bores where the body of a probe type may not reach. It can also be used for comparative measurement.

Small and lightweight.

Can easily and accurately measure the long-narrow or concave portions and the inside and outside diameters where dial indicator are hard to reach.

High sensitivity and quick response.

Steel and ruby styli are optional.
